We lay down for a nap. She falls asleep, then I get up usaually. But we often have aritual we go through first. She "wants daddy's arm", which means she wants my arm under her head. "Roll over and hold me" is the next request. As she struggles to go to sleep, her next request I must deny. Our faces are inches apart when she chimes "stop breathing". I am an agreeable dad, but I draw the line there.
